  • Publication number: 20240092415
    Abstract: An HOD device, comprising: a framework; covering material, covering the frame work; at least one conductive region, provided on or in the covering material; wherein the conductive region is coupled to a capacitance detection circuit or a predetermined voltage level. The HOD device can be a vehicle control device such as a steering wheel. The conductive region comprises conductive wires which can be threads of the covering material. By this way, the arrangements of the conductive wires can be changed corresponding to the size or the shape of the frame work or any other requirements. Also, the interference caused by unstable factors can be improved since the conductive wires can be coupled to a ground source of the vehicle to provide a short capacitance sensing path.

    Abstract: A device for auto baud rate detection includes an edge trigger, a counter, at least one register and a central processing unit. The edge trigger detects whether a potential of a transmitted signal is raising or falling. The counter is connected to the edge trigger and uses the edge trigger to count pulse widths of the transmitted signal. The register is connected to the counter and stores the pulse widths. The central processing unit is connected to the register, compares the pulse widths so as to identify a minimal pulse width, and calculates a baud rate according to the minimal pulse width by using a probability density function. Thereby, the device is advantageous for lowering hardware costs, increasing use flexibility, reducing configuration limitation and ensuring accurate baud rate detection.

In the method the red, green and blue (RGB) of color samples are input as features of training samples and are automatically classified by way of SOM NN. Afterwards, the outcomes of SOM NN are respectively delivered to various BP NN for further learning; and the map relationship of the input and the output defines the X,Y, Z corresponding the x, y and z values of a coordinate system of the standard color samples of RGB and IT8. By way of the above learning structure, a non-linear model of color identification can be set up. After color samples are self organized and classified by SOM NN network, data can be categorized in clusters as a result of characteristic difference thereof.
